Abstract

The invention relates to a stagewise drum screen device for sand grading separation, belongs to the technical field of processing building materials and aims at solving the technical problems how to realize grading screening of sand grading separation and rapid change of a screen mesh. The stagewise drum screen device for sand grading separation comprises a rack, a rotary shaft, a drive part used for driving the rotary shaft to rotate, a drum frame and a plurality of screen mesh components used for screening sand stones in a grading manner, wherein the rotary shaft is rotationally connected to the rack; the drum frame sleeves and is fixedly connected with the rotary shaft; a plurality of openings which are sequentially formed in the axial direction of the rotary shaft are formed in the side surfaces of the drum frame; and the screen mesh components are detachably connected to the drum frame and in addition covers the corresponding opening. According to the stagewise drum screen device for sand grading separation, each screen mesh component has the advantages of very convenience in disassembling, easiness in cleaning and changing, capabilities of reducing dusts and protecting workers from being hurt by splashing sand grains and convenience in changing the screen mesh components.

Description

technical field [0001] The invention belongs to the technical field of building material processing, and relates to a screening device, in particular to a graded drum screen device for sand gradation separation.
